British qualifier Laura Robson bounced back from one set down to dump world number 49 Maria Jose Martinez Sanchez out of the tournament and progress to the second round.
Qualification was plain sailing for the British number four but she met her match when drawn against Martinez Sanchez in the opening round of the main women’s singles draw.
The Spaniard took the first set comfortably by six games to three but, after getting this far, Robson was not about to bow out without a fight.
The world number 111 broke early in the second set to kick-start the comeback that British fans were hoping for.
She drew level in the match by taking the second set 6-2 and repeated the score line in the third to seal the victory and a place in the second round.
Speaking after her win, Robson said, “I was really happy with the way I played. I was patient enough in the rallies and I didn’t let her dictate the points. She was coming to the net a lot so I had to keep her at the back of the court and I did that well.
“I spoke to my coach about what I can change after the first set because I didn’t think I was doing that much wrong.
“I lost to her before, quite easily actually, so I’m just really pleased with how I returned and how I competed. It was a big win but I know that I’m capable of wins like that and I can do better.”
She will face Ekaterina Makarova in the final eight after the Russian beat world number four and second seed Petra Kvitova in her first round contest.
